How to rank the heat resistance grade of epoxy glass fiber tube?
2021-08-23

The epoxy glass fiber tube is made of thermosetting epoxy resin as the main raw material, air is used as the dispersion medium, and the powder is evenly sprayed on the surface of the preheated steel tube with the help of high-speed airflow and electric attraction. Under the action of high temperature, the powder melts into an anti-corrosion layer of uniform thickness.

The coating has no solvent pollution, no need to consider fire protection measures during construction; fast curing speed; thickness can be from tens of microns to hundreds of microns, with good toughness, no cracks when the pipe is bent; its advantage is that it has great adhesion to the metal surface , Good bonding performance, resistance to cathodic disbondment; easy to repair; strong resistance to soil stress, suitable for most severe corrosive environments such as high salt, high alkali, and cold.

It is widely used in the coating of the inner wall of water supply equipment such as drinking water tanks, water pipes, water tanks, water towers, and used in the cargo holds of sugar and grain. Used in coal mine drainage systems, gas drainage pipes, positive and negative pressure ventilation pipes, fire-fighting pipes and long-term supply of plastic sprinkler systems. It can also be used as the inner wall coating of swimming pools, cooling towers of power plants, and metal and concrete filled with fuel oil and gasoline.

Epoxy fiberglass tube is made of electrical alkali-free glass fiber cloth impregnated with epoxy resin. After baking and hot pressing in a forming mold, the cross-section is shaped. The glass cloth rod has a high mechanical performance. Dielectric properties and good machinability. The heat resistance grade can be divided into B grade (130 degrees), F grade (155 degrees), H grade (180 degrees), and C grade (above 180 degrees). It is suitable for insulating structural parts in electrical equipment, and can be used in damp environment and transformer oil. The surface should be flat and smooth, free of bubbles, oil stains and impurities. Color unevenness, scratches, slight height inequality that do not hinder use are allowed. Laminated glass cloth rods with a diameter of more than 25mm are allowed to have cracks on the end or section that do not hinder use.
